Abstract
The deployment of wireless technologies in the radiology field requires development of radiolucent materials allowing wireless communication. In this paper, both the radiolucency (X-rays) and Electro-Magnetic (EM) properties of the conductive polymer poly (3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) are investigated to address wireless applications in the field of the radiology. A model was developed to predict the PEDOT:PSS performance and assess the interest of this material in terms of radiolucency characteristics and Electro Magnetic (EM) radiation efficiency. A PEDOT:PSS antenna operating in the Radio-Frequency Identification (RFID) Ultra High Frequency (UHF) band, was realized to experimentally validate abilities of PEDOT:PSS. These performances are compared with those produced by a similar antenna made of conventional materials such as copper. Experimental results validate the numerical model of the designed structure. This paper demonstrates the potential of polymer materials in the field of x-ray imaging.
Highlights
Wireless technologies are more and more involved in medical fields in general and radiology applications in particular [1]: further and further wireless technologies are involved in hospitals, to record vital signs for example [2] [3] [4]

The radiolucency is an important property of a sensor in radiology to avoid image artifacts caused by the x-ray radiation used in combination with dense materials
Summary
Wireless technologies are more and more involved in medical fields in general and radiology applications in particular [1]: further and further wireless technologies are involved in hospitals, to record vital signs for example [2] [3] [4]. They can allow patient monitoring at his bedside or during transport. The majority of hospitalized patients need x-rays or a scan: wireless radiolucent systems may find application in radiology. Wireless radiolucent sensors are systems of interest to assist the medical personal
